You can actually configure the RAC interconnect to over your public network and it will work; however, you really want a private dedicated connection for performance reasons. If your system comes under load the current configuration may well become an issue.
Just because the current set up is working satisfactory does not mean that ths issue should not be addressed, but if the current setup is working fine you need to ask how likely is the load to increase? Are there currently times in our processing where the interconnect performance is an issue. How busy is the subnet? What else uses the same subnet? How likely is conflict?
It may be you have no pressing need to make any change.
